How to add dependency via arn in terraform?
问题
我有Terraform代码，用于创建一些AWS资源。例如，我创建一个S3存储桶，并根据它创建另一个资源，或者依赖于这个S3资源。我知道Terraform会确定这个新对象资源依赖于第一个S3存储桶资源，因为我已经将这个=> aws_s3_bucket.s3.id 传递给新资源。我不确定这是ARN、存储桶名称还是Terraform维护的某个内部ID。但是是否可以通过传递ARN或其他内容来添加这种依赖关系呢？
假设我有一个已经在其他地方创建的存储桶名称，我可以在下面的示例中简单地传递它的ARN，所以不是aws_s3_bucket.s3.id，而是传递存储桶名称，如var.bucket name，这样会起作用吗？
我尝试过传递这个=> aws_s3_bucket.s3.id，这样可以工作。但我想知道是否可以传递ARN。
英文:
I have terraform code , to create few aws resources. for example . i create a s3 bucket and create another resource based on or which depends on this s3 resource. I know terraform will figure out that this new object resource is dependent on the first s3 bucket resource, as i have passed this => aws_s3_bucket.s3.id , to the new resource. I'm not sure if this is a arn or bucket name or some intrinsic id that terraform maintains. but is it possible to add such dependency by passing in arn or something else?
so say , i had a bucket name that is already created somewhere else, and I can simply pass its arn in my example below , so instead of aws_s3_bucket.s3.id , i can pass bucket name , as var.bucket name
will that work?
resource "aws_s3_bucket" "s3" {
bucket = "s3-bucket-name"
acl = "private"
...
}
resource "aws_s3_bucket_object" "init" {
bucket = aws_s3_bucket.s3.id
key = "bin.tar.gz"
....
}
I've tried passing this => aws_s3_bucket.s3.id, which works. but want to know if i can pass an arn

aws_s3_bucket.s3.id实际上是存储桶名称；aws_s3_bucket_object.init.bucket预期的是存储桶名称，传递存储桶 ARN 将导致错误；aws_s3_bucket_object.init.bucket预期的是一个字符串，您可以以任何方式传递它，只要它是有效的字符串存储桶名称，var.bucket完全可行。
英文:
aws_s3_bucket.s3.idis actually the bucket name;aws_s3_bucket_object.init.bucketexpects a bucket name, passing a bucket ARN will result in an error;aws_s3_bucket_object.init.bucketexpects a string, it doesn't matter how you pass it there, sovar.bucketwill totally work as long as it's a valid string bucket name.
